EDGE-INKING MACHINE.

Specification of Letters Patent.

Patented Jan. 10, 1911.

To all whom it may concern:

Be it known that I, ANDREW W. REDI'N, a citizen of the United States,residing at Rockford, in the county of Winnebago and State of Illinois,have invented certain new and useful Improvements in Edge-InkingMachines, of which the following is a specification. j y

This invention relates to machines for applying ink or blacking to theedges of shoe soles and heels during the process of manufacturing shoes.

One of the objects of the invention is to produce means for rapidly andevenly applying ink to the edges of a sole, including the top of theportion of the sole which projects beyond the vamp and the beveled'surfaces of the sole.

Another object is to prevent the ink from being applied to the vamp.

A further object is to provide means for stirring the supply of ink toprevent settling and to keep the-ink of uniform consistency.

A further object is to provide means for regulating the flow of ink tothe ink-apply in@ device.

The invention also relates to the other features of improvement hereinset forth.

In the accompanying drawings, Figure. 1 is a side elevation, with partsin section, of a machine embodying the features. of my. in-

vention. Fig. 2 is a front elevation of the machine. Fig. 3 is a'sectionon line 3 of Fig. 1. Fig. 1 is a section online 4 t of Fig. 1. Fig. 5 isa sectional view through one of the valves, the view being taken in thelane of the axis ofthe valve. Figs. 6 and? the latter in open and closedposition, respectively. Fig. 8 is a detail yperspective view of thebrush used in inking the sole. Fig. 9 is a sectional view of said brush,and illustrates the manner of applying the shoe thereto. Fig. 1() is arear side elevation of said brush. Figs. 11 and 12 are sections on lines11 and 12, respectively, of Fig. 9.

The embodiment herein shown of my invention comprises a framework whichmay consist of the base 1, said base having lugs 2 thereon by means ofwhich the machine m'ay be secured to a bench or other suitable support.Rising from the base 1 is a bracket 3 upon which is supported areservoir 4 for the ink or dye. Said reservoir, in the form are detailviews of the valve, showing l lower end of the reservoir 4 is a boss 5having an outlet passage 6 therein and adapted 4 to be inserted into aslot 7 in the upper end of the bracket 3. The reservoir is removablysecured to the bracket by means of a lock nut 8 turned upon thescrew-threaded lower end of the boss 5 and arranged to clamp thereservoir to the bracket. The lock nut 8 is provided with an operatingarm 9 by means of which it may be given a partial rotation to release orclamp the reservoir. From the reservoir 4: the ink flows to anoscillatory or swinging brush which is carried by a lever 10 pivotedintermediate its ends upon a stud 11 having a screw-thread connectionwith the base or frame of the machine. The upper end of the lever 10 isbifurcated, as shown in Figs. 1 and 2 at 12, the bifurcation receiving aslidable block 13 which is carried by a crank pin 111 upon the forwardend of the shaft 15 carried by the base 1. On the shaft 15 is a tightpulley 16 and a loose pulley 17 to receive a drive belt 18. It will beseen that as the shaft 15 is rotated, the lever 10-will be oscillatedupon its pivot 11.

The brush for applying the ink to the sole comprises, in this instance,a back 19 (Figs. 8 and 9) suitably curved so that the tufts of bristles2O shall be adapted to engage properly the edge of a sole and the top ofthe portion of the sole projecting beyond the vamp. The back 19 is'attached by means of screws 21 to a block 22 having a shallow recess 23therein, said recess communicating with the concave face of the back 19by means of ducts 24. The block 22 is rigidly secured to a block 25havin-g a shank 26 adapted to be inserted into a socket 27 in the loweren d of the lever 10, said shank being removably clamped in said socketby means of a .set screw 28.

For applying ink to the heel, I use a brush (not shown) having a surfaceconforming to the shape of the edge of the heel, the heelnking brushbeing interchangeable with the sole brush.

A valve 29 (Fig. 5) located intermediate the reservoir and the brushcomprises a plug 30 having a screw-threaded stem 31, which stem isturned into a screw-threaded opening in the stud 11. A port 30u isformed of the stud 11 by means of an operating arm 33. On the forwardend of the valve .plug 30 Vis 'a.finger'piece-"34 The valve casing 35 ismounted to swing upon the valve plug 30, being held in proper relationVto said Y valve plug by means of a nut 36. Extending through the casing35 is a p assage-37. On the lower end of the valve casing 35 1s a nipple33' which communicates with the chambered brush back by means of a tube39 attached to the brush. The tube 39 has a slip connection with thenipple 3S so that Vthe brush may be readily removed and another form ofbrush substituted. A pin 40 fixed in the lever 10 and having a forkedforward end which embraces'the ni-pple 3S causes the valve casing 35 tooscillate with said lever and the brush.

To the lower end of the boss 5 on the reservoir 4 is fixed a valve 41comprising a valve casing 42 and an oscillatory valve plug 43. rl`hevalves 29 and 41 are flexibly connected together by means of a tube 44of rubber or the like, the ends of said tube being slipped over thenipples 45 and 46 upon said valves. rIhe oscillatoryv valve plug 43 hasan operating arm 47 fixed thereto. To the rear end of the arm 47 isattached a spring 48 which tends to rock the valve plug 43 in thedirection to close the valve. The arm 47 may be manually operated in anysuitable way toopen the valve, as, for example, by means of a flexibleconnection49 extending to a treadle (not shown). y,

lVhen the opening 30a through` the valve v plug 30 extends horizontally,as shown in Fig. 5, the oscillations of the valve casing 35 do not bringthe passage 37 into register with said opening, and the valve 29therefore is closed even though the shaft 15 may beA rotating. Vhen thevalve plug 30 is turnedeither to the right or the left by means of thefinger piece 34, the oscillations of the valve casing 35 will bring thepassage 37 therein into register with the opening 30a, the extent towhich said openings register, depending upon the extent to which the`valve plug 30 is turned from the horizontal by the operator. It will beseen from Figs. I 6 and 7 that when the lever-10 swings in one fdirection, the valve 29 will open, and that when the lever swings in theopposite direction the valve will close. VVThe relative` movementbetween the valve casing 29 and the valve plug 30 prevents the ink fromclogging 1n said valve.

To indicate the extent to which the valve i 29 is opened, a graduatedplate 50 may be provided,- sa-id plate being fixed to the frame i of themachine, the valve plug 30 being provided with a pointer 51 arranged toswing across the face of said graduated plate.

i Inorder to prevent the application of the ink to the vamp, I provide aguard plate 52 which is secured to the machine frame. Said guardlate'lies in front of the forward portion o the brush.

In order to agitate the contents of the reservoir 4 and thereby keep theink of uniform consistency, I provide a )erforated dasher disk 53 fixedto the end of a stem 54 which extends through a central opening 55 inthe cap 56 of the reservoir. To the lower side of the disk 53 is fixed acentral pin 57 arranged to enter the outlet opening 6 to preventclogging ofsaid opening and to positively force ink therethrough. Thedasher disk and the pin 57 are reciprocated by means comprising, in thisinstance, a rod 58 secured to the stem 54 by means of a screw 59, therod 5S being vertically reciprocable in a guide 60 fixed to the machineframe. The lower end of the rod 58 is connected rto a wrist pin 61 upona sprocket wheel 62 by means of a connecting rod 63. The sprocket wheel62 is mounted upon a shaft 64 and receives a chain 65 extending over asprocket wheel 66 fixed upon the shaft 15. then the shaft 15 is rotated,the rod 58 is reciprocated to operate the disk 53 and the pin 57.

In practice, it is desirable to place in the reservoir 4 a quantity ofthe solution sufficient for a days work, and to remove the reservoir atnight in order that it may be thoroughly cleaned and a fresh supply ofink placed therein when beginning `the following days work. Thereservoir may be removed by turning the lock nut 8 to release the lowerend of the reservoir, removing the screw 59, and disconnecting therubber tube 44 from the nipple 46. The cap 56 may have a slip connectionwith the upper end of the reservoir so that it may be readily removedand replaced in replenishing the supply of ink.

In operation, the operator opens the valve 29 by turning the valve plug30 into, say, the position said plug is shown to occupy in Fig. 6. Whenhe is ready to present a shoe to the machine, the operator opens thevalve 41, as by means of the treadle hereinbefore alluded to. The shaft15 being rotated, the ink will flow to the swinging brush. The operatornow takes a shoe, preferably with a last a therein, and presents theedge of the sole Z) to the brush, as indicated in Figs. 1

and 9. The gua-rdv plate 52 not only keeps the ink olf the vamp c, butalso serves as a guide as the shoe is moved by the operator, the saidguardlying in the angle between the vamp and the sole. The back of thesole brush is curved so as to present the ends of the tufts of bristlessquarely to the sole. As the operator moves the edge of the sole alongunder the rapidly swinging brush, t-he latter spreads the ink evenlyupon the vertical edge of the sole and the top of the project* ingportion thereof, as well as upon any beveled surfaces that may be formedon the edge portion of the sole. For inlring the heel, a brush having aface conforming to the shape of the heel-edge is substituted for thebrush 19 20, the heel brush having yan attaching stem and a tube similarto the stem 26 and the tube 39 of the sole brush.

I would have it understood that I desire not to be limited to thedetails of construction herein shown and described, for variousmodifications will occur to persons skilled in the art.
